The Field Mortar Battery has 4 mortars, each with 3 carriages—one for travelling, one for firing, and one carrying firing platform. It has no ammunition wagons.
The function of Field Mortars is to attack Barrier Forts, or strongly defended positions. These Batteries will probably be allotted to Armies, not Army Corps.
